Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 55704-78-4 N99176196Z 2,5-Dimethyl-2,5-dihydroxy-1,4-dithiane 2,5-Dimethyl-1,4-dithiane-2,5-diol 1,4-Dithiane-2,5-diol, 2,5-dimethyl- 2,5-Dimethyl-2,5-dihydroxy-p-dithiane 2,5-Dimethyl-p-dithiane-2,5-diol EINECS 259-770-3 FEMA No. 3450 2-Mercaptopropanone NSC 176174 UNII-N99176196Z.

55704-78-4 N99176196Z 2,5-Dimethyl-2,5-dihydroxy-1,4-dithiane 2,5-Dimethyl-1,4-dithiane-2,5-diol 1,4-Dithiane-2,5-diol, 2,5-dimethyl- 2,5-Dimethyl-2,5-dihydroxy-p-dithiane 2,5-Dimethyl-p-dithiane-2,5-diol EINECS 259-770-3 FEMA No. 3450 2-Mercaptopropanone NSC 176174 UNII-N99176196Z (CAS 55704-78-4), molecular formula C6H12O2S2 and molecular weight 180.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 55704-78-4 N99176196Z 2,5-Dimethyl-2,5-dihydroxy-1,4-dithiane 2,5-Dimethyl-1,4-dithiane-2,5-diol 1,4-Dithiane-2,5-diol, 2,5-dimethyl- 2,5-Dimethyl-2,5-dihydroxy-p-dithiane 2,5-Dimethyl-p-dithiane-2,5-diol EINECS 259-770-3 FEMA No. 3450 2-Mercaptopropanone NSC 176174 UNII-N99176196Z (C6H12O2S2) is characterized by a sulfone group, 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), 55704-78-4 N99176196Z 2,5-Dimethyl-2,5-dihydroxy-1,4-dithiane 2,5-Dimethyl-1,4-dithiane-2,5-diol 1,4-Dithiane-2,5-diol, 2,5-dimethyl- 2,5-Dimethyl-2,5-dihydroxy-p-dithiane 2,5-Dimethyl-p-dithiane-2,5-diol EINECS 259-770-3 FEMA No. 3450 2-Mercaptopropanone NSC 176174 UNII-N99176196Z 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.
