Catalogue / RAD-150
RAD-150
Also written as TLB-150 benzoate.
An ester prodrug rather than a receptor ligand in its own right, sold as the benzoate of a related modulator and documented far less consistently than anything else in this class.
| Molecular target | Androgen receptor, after hydrolysis |
| Class | Androgen receptor modulators |
| Determination | Small molecule analysis, reference standard sourced to order |
| Price | 527 USD |
RAD-150 is identified against a certified reference standard rather than against a published mass, because the composition supplied under this name is not consistently documented and no verified figure exists to publish. Purity is reported separately by reversed-phase chromatography and describes the chromatographable fraction only.
| No mass figure is published on this page. A public chemical database queried on this trivial name returns an entirely unrelated compound, and a name match is not a structure, so that result was rejected rather than transcribed. Identity is established against a certified reference standard at the time of analysis. |
| An ester hydrolyses. Material stored in a protic solvent partly reverts to the parent alcohol, so both species have to be reported and a chromatogram showing a single clean peak is a question rather than an answer. |
| The parent and the ester differ by 104 daltons and are frequently sold interchangeably under either name. A laboratory that assumes which one it received will report a mismatch it cannot account for. |
Every compound fails in its own way. A generic peptide method applied without regard to these specifics produces a number that looks like a result and is not one.
Non-steroidal small molecules, most of them a single enantiomer of an aryl propanamide. They are not peptides and almost nothing carried over from peptide work applies: there is no amide backbone to detect at 214 nm, the molecules are a fraction of the mass of the smallest peptide in this catalogue, and the impurity that matters most is a mirror image that no achiral column separates from the target.
LC-MS identity against a certified reference standard, acquired in the ionisation polarity the compound actually responds in rather than in whichever polarity the instrument was left in. Purity by HPLC-UV at the compound's own absorbance maximum, not at 214 nm. Enantiomeric purity is a separate determination on a chiral stationary phase and is reported as a separate figure, because an achiral method cannot see it.
Where the delivered milligram figure matters rather than the percentage, assay against a certified reference standard gives content directly, and where no such standard exists quantitative NMR against a certified internal standard gives an absolute purity that needs no standard of the analyte at all.

What is the molecular weight of RAD-150?
No molecular weight is published for RAD-150 on this page, because the composition of commercially supplied material varies between suppliers and an unverified figure on an analytical site is worse than an absent one. Identity is established against a certified reference standard at the time of analysis.
How is RAD-150 tested for purity and identity?
LC-MS identity against a certified reference standard, acquired in the ionisation polarity the compound actually responds in rather than in whichever polarity the instrument was left in. Purity by HPLC-UV at the compound's own absorbance maximum, not at 214 nm. Enantiomeric purity is a separate determination on a chiral stationary phase and is reported as a separate figure, because an achiral method cannot see it. Purity is an area ratio measured at the compound's own ultraviolet maximum, and it describes the chromatographable fraction only. It says nothing about which enantiomer is present, because mirror images are not separated by an achiral column.
What goes wrong when RAD-150 is analysed?
No mass figure is published on this page. A public chemical database queried on this trivial name returns an entirely unrelated compound, and a name match is not a structure, so that result was rejected rather than transcribed. Identity is established against a certified reference standard at the time of analysis.
What does RAD-150 analysis cost at ANALYTON?
Small molecule analysis, reference standard sourced to order is priced at 527 US dollars, covering the determinations described on this page. Content, safety and elemental determinations are ordered alongside and are priced separately on the price list.
