Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 60856-85-1 LZU52L66UC Ethyl 2-hydroxy-4-methylvalerate, (2S)- UNII-LZU52L66UC (S)-(-)-Ethyl leucate Ethyl (S)-2-hydroxyisocaproate Ethyl 2-hydroxy-4-methylpentanoate, (-)- Ethyl 2-hydroxyisocaproate, (S)- Ethyl L-2-hydroxyisocaproate Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (2S)- Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (S)-.

60856-85-1 LZU52L66UC Ethyl 2-hydroxy-4-methylvalerate, (2S)- UNII-LZU52L66UC (S)-(-)-Ethyl leucate Ethyl (S)-2-hydroxyisocaproate Ethyl 2-hydroxy-4-methylpentanoate, (-)- Ethyl 2-hydroxyisocaproate, (S)- Ethyl L-2-hydroxyisocaproate Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (2S)- Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (S)- (CAS 60856-85-1), molecular formula C8H16O3 and molecular weight 160.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 60856-85-1 LZU52L66UC Ethyl 2-hydroxy-4-methylvalerate, (2S)- UNII-LZU52L66UC (S)-(-)-Ethyl leucate Ethyl (S)-2-hydroxyisocaproate Ethyl 2-hydroxy-4-methylpentanoate, (-)- Ethyl 2-hydroxyisocaproate, (S)- Ethyl L-2-hydroxyisocaproate Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (2S)- Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (S)- (C8H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

As a certified reference material (CRM), 60856-85-1 LZU52L66UC Ethyl 2-hydroxy-4-methylvalerate, (2S)- UNII-LZU52L66UC (S)-(-)-Ethyl leucate Ethyl (S)-2-hydroxyisocaproate Ethyl 2-hydroxy-4-methylpentanoate, (-)- Ethyl 2-hydroxyisocaproate, (S)- Ethyl L-2-hydroxyisocaproate Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (2S)- Pentanoic acid, 2-hydroxy-4-methyl-, ethyl ester, (S)- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
