Chemical Structure

(10s,11s)-6,6,10,11-tetramethyl-4-propyl-10,11-dihydro-2h,6h,12h-dipyrano[2,3-f:2',3'-h]chromene-2,12-dione 18489-25-3 KST-1A2220 CAS 18489-25-3 chemical structure

Description

As a certified reference material (CRM), (10s,11s)-6,6,10,11-tetramethyl-4-propyl-10,11-dihydro-2h,6h,12h-dipyrano[2,3-f:2',3'-h]chromene-2,12-dione 18489-25-3 KST-1A2220 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.

(10s,11s)-6,6,10,11-tetramethyl-4-propyl-10,11-dihydro-2h,6h,12h-dipyrano[2,3-f:2',3'-h]chromene-2,12-dione 18489-25-3 KST-1A2220 (CAS 18489-25-3), molecular formula C8H12N4 and molecular weight 164.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (10s,11s)-6,6,10,11-tetramethyl-4-propyl-10,11-dihydro-2h,6h,12h-dipyrano[2,3-f:2',3'-h]chromene-2,12-dione 18489-25-3 KST-1A2220 (C8H12N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
