62961-64-2 Diisopropyl (S-(R*,R*))-tartrate Butanedioic acid, 2,3-dihydroxy-, 1,4-bis(1-methylethyl) ester, (2S,3S)- Butanedioic acid, 2,3-dihydroxy-, bis(1-methylethyl) ester, (2S,3S)- (S-(R*,R*))-2,3-Dihydroxybutanedioic acid, bis(1-methylethyl) ester EINECS 263-771-4 CAS 62961-64-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 62961-64-2 Diisopropyl (S-(R*,R*))-tartrate Butanedioic acid, 2,3-dihydroxy-, 1,4-bis(1-methylethyl) ester, (2S,3S)- Butanedioic acid, 2,3-dihydroxy-, bis(1-methylethyl) ester, (2S,3S)- (S-(R*,R*))-2,3-Dihydroxybutanedioic acid, bis(1-methylethyl) ester EINECS 263-771-4.

62961-64-2 Diisopropyl (S-(R*,R*))-tartrate Butanedioic acid, 2,3-dihydroxy-, 1,4-bis(1-methylethyl) ester, (2S,3S)- Butanedioic acid, 2,3-dihydroxy-, bis(1-methylethyl) ester, (2S,3S)- (S-(R*,R*))-2,3-Dihydroxybutanedioic acid, bis(1-methylethyl) ester EINECS 263-771-4 (CAS 62961-64-2) is a high-purity analytical reference standard with the molecular formula C10H18O6 and a molecular weight of 234.25 g/mol.

Based on its molecular formula C10H18O6, 62961-64-2 Diisopropyl (S-(R*,R*))-tartrate Butanedioic acid, 2,3-dihydroxy-, 1,4-bis(1-methylethyl) ester, (2S,3S)- Butanedioic acid, 2,3-dihydroxy-, bis(1-methylethyl) ester, (2S,3S)- (S-(R*,R*))-2,3-Dihydroxybutanedioic acid, bis(1-methylethyl) ester EINECS 263-771-4 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 234.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
