(1S)-1-[5-(1-Methyl-4-{4-[(3-methylpyridin-2-yl)[(3R)-piperidin-3-yl]carbamoyl]phenyl}-1H-pyrazol-5-yl)-2H-1,2,3,4-tetrazol-2-yl]ethyl 2-methylpropanoate CAS 1632250-94-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S)-1-[5-(1-Methyl-4-{4-[(3-methylpyridin-2-yl)[(3R)-piperidin-3-yl]carbamoyl]phenyl}-1H-pyrazol-5-yl)-2H-1,2,3,4-tetrazol-2-yl]ethyl 2-methylpropanoate.

(1S)-1-[5-(1-Methyl-4-{4-[(3-methylpyridin-2-yl)[(3R)-piperidin-3-yl]carbamoyl]phenyl}-1H-pyrazol-5-yl)-2H-1,2,3,4-tetrazol-2-yl]ethyl 2-methylpropanoate (CAS 1632250-94-2) is a high-purity analytical reference standard with the molecular formula C29H35N9O3 and a molecular weight of 557.65 g/mol.

(1S)-1-[5-(1-Methyl-4-{4-[(3-methylpyridin-2-yl)[(3R)-piperidin-3-yl]carbamoyl]phenyl}-1H-pyrazol-5-yl)-2H-1,2,3,4-tetrazol-2-yl]ethyl 2-methylpropanoate (C29H35N9O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
