5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-3-(2-methoxyphenoxy)-4-methyl-1H-pyrrol-2-yl acetate (CAS 112309-83-8), molecular formula C12H18O4Si and molecular weight 254.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-3-(2-methoxyphenoxy)-4-methyl-1H-pyrrol-2-yl acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-3-(2-methoxyphenoxy)-4-methyl-1H-pyrrol-2-yl acetate 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.
