Description

Product Name: Amphoteric Polyacrylamide
CAS Number: 9003-05-8
Molecular Formula: (C₃H₅NO)ₙ
Molecular Weight: Variable (typically 3–22 million Da, depending on polymerization)
Appearance: White to off-white granular powder

Amphoteric polyacrylamide is a linear, water-soluble copolymer synthesized from acrylamide and ionic comonomers, carrying both positively and negatively charged functional groups along its macromolecular chain. Unlike physical blends of cationic and anionic polymers, this single-chain zwitterionic architecture prevents mutual precipitation and ionic cross-linking, ensuring stable performance across a broad pH range of approximately 3 to 12. The material exhibits high solubility in aqueous media and is practically insoluble in nonpolar solvents. Its charge density and ionic character are adjustable during synthesis, allowing tailored charge neutralization and bridging flocculation behavior. Functionally, this polymer acts simultaneously as a coagulant and a high-efficiency flocculant, generating dense, shear-resistant flocs that accelerate solid-liquid separation in centrifuges, screw presses, and clarifiers. It is extensively employed in municipal and industrial wastewater treatment, papermaking retention and drainage systems, oilfield drilling fluids, and mineral processing. Its dual-charge character enables effective treatment of complex effluents with mixed colloidal charges and high salinity, where single-charge polymers often fail. The product should be stored in a cool, dry, well-ventilated area away from direct sunlight, moisture, and strong oxidizing agents.

Conclusion	It complies to the standard

For regulatory compliance (e.g., USP, EP, JP), raw material Vidarabine must meet several rigorous standards:

Assay (by HPLC): 98.0% – 102.0% on an anhydrous basis.
Related Substances: Limits for specific impurities, notably Ara-Hx (NMT 2.0%), as well as any unspecified individual impurity (NMT 0.1%) and total impurities (NMT 2.0%).
Residual Solvents: Must comply with ICH Q3C guidelines (Class 1 and 2 solvents limited or absent).
Heavy Metals: NMT 20 ppm (typically lower for injectable grades).
Water Content (Karl Fischer): NMT 6.0% (the material is hygroscopic to a degree).
Microbial Limits: Total aerobic microbial count (TAMC) ≤ 1000 CFU/g, absence of S. aureus, P. aeruginosa, and Candida albicans.

As a high-purity pharmaceutical intermediate, L-Tyrosine Ethyl Ester Hydrochloride is predominantly utilized in the chemical synthesis of bioactive peptides, dopamine analogs, and melanin precursors. Its excellent solubility profile makes it an ideal chiral building block for asymmetric synthesis and a critical substrate in enzymatic reactions. Available in purity grades of ≥98% (HPLC), it meets stringent requirements for R&D and cGMP manufacturing processes. Reliable supply ensures batch-to-batch consistency for long-term project scalability.

Vidarabine is classified as a potential reproductive hazard and an irritant. Safety Data Sheets (SDS) mandate the following:

Hazard Statements (H360): May damage fertility or the unborn child (Category 1B).
Precautionary Measures: Use fume hoods and wear impermeable gloves (e.g., nitrile), lab coats, and safety goggles. Avoid generating airborne dust.
First Aid: In case of skin contact, wash immediately with copious soap and water. If inhaled, move to fresh air.
Storage: Store in tightly sealed, light-resistant containers at 2°C to 8°C (refrigerated) for long-term stability. Avoid freezing.

While superseded by newer nucleoside analogs (Acyclovir, Ganciclovir) for systemic use due to better bioavailability and lower toxicity, Vidarabine retains niche value. Its primary current application is ophthalmic ointment (3%) . Pharmacokinetically, the raw material has poor oral bioavailability (<10%) and is rapidly deaminated in the gastrointestinal tract, necessitating parenteral or topical administration.

Vidarabine API is a well-characterized, stable crystalline nucleoside analog. While its systemic use has declined, it remains a critical raw material for topical antiviral ophthalmic preparations, particularly where resistance to other agents occurs. Manufacturers must strictly control impurities (especially Ara-Hx) and water content to ensure final drug product efficacy.

ECHEMI Editorial Reference

Polyacrylamide is relatively stable to heat with its solid only being softened at 220~230 °C and its solution subjecting to significant degradation only at above 110 °C. Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water. It can be cross-linked by the
