(S)-2-((4-Chloro-6-((4-methoxyphenyl)thio)pyrimidin-2-yl)amino)-4-methylpentanoic acid CAS 825647-48-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-((4-Chloro-6-((4-methoxyphenyl)thio)pyrimidin-2-yl)amino)-4-methylpentanoic acid.

(S)-2-((4-Chloro-6-((4-methoxyphenyl)thio)pyrimidin-2-yl)amino)-4-methylpentanoic acid (CAS 825647-48-1), molecular formula C17H20ClN3O3S and molecular weight 381.88 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-2-((4-Chloro-6-((4-methoxyphenyl)thio)pyrimidin-2-yl)amino)-4-methylpentanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
