Shijiazhuang Chirals Chemical Co., Ltd

Shijiazhuang Chirals Chemical Co., Ltd is based in China and lists seven active products in its catalogue. The company classifies its offerings under Industrial Chemicals and Laboratory Reagents, indicating a focus on specialty organic compounds used in synthesis and analytical work. The product portfolio includes chiral alcohols such as (R)-(-)-3-Quinuclidinol and several methyl ester derivatives of hydroxybutanoic acid, as well as a trihydroxybenzaldehyde monohydrate. All items fall within the organic chemical segment that is typically coded under HS Chapter 28 for organic compounds. The supplier is recorded as an imported tier with a harbor trust rating, suggesting established logistics capabilities for overseas shipment.

The listed chemicals comprise enantiomerically pure intermediates and functionalized esters that are common inputs for pharmaceutical intermediates, agrochemical synthesis, and fine‑chemical research. Examples such as (-)-2,3-O-Isopropylidene-D-threitol and the various methyl 3‑hydroxybutanoate esters are often required with optical purity above 95 % and overall chemical purity of 98 % or higher. The presence of a monohydrated aromatic aldehyde expands the range to include reagents for condensation and polymer precursor work. Buyers can expect these substances to be shipped in compliance with standard HS‑28 classifications and to be accompanied by material safety data sheets.

The catalogue presents seven distinct chiral and functionalized organic compounds, all of which are standard reagents in synthetic organic chemistry. Products such as (R)-(-)-3-Quinuclidinol and the methyl 3‑hydroxybutanoate series are typically supplied as powders or low‑melting solids, with common packaging in sealed polyethylene bags or amber glass bottles to protect optical activity. In the broader market, chiral alcohols are graded by enantiomeric excess (ee) and optical rotation values, while ester intermediates are evaluated for ester purity, water content, and residual acid levels. Industry practice often requires a minimum of 99 % assay purity and verification by chiral HPLC or polarimetry.

Laboratory reagents like 3,4,5‑Trihydroxybenzaldehyde monohydrate are used in analytical protocols and polymer chemistry, where moisture content (typically below 0.5 %) and particle size distribution are critical. Buyers generally look for compliance with ISO 9001 quality management and may request certificates of analysis (CoA) that detail NMR, LC‑MS, and IR data. The product mix reflects a niche focus on high‑purity, stereospecific chemicals that support research and development in pharmaceuticals and fine chemicals.
