Solution Approach
RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.

Sulfamic Acid
CAS 5329-14-6
Acids & Salts
Cleaning / Degreasing
2967 (SULFAMIC ACID) · Class Sulfamic acid (H3NO3S) is a solid INORGANIC acid - not organic - that descales carbonate and oxide scale with low fuming and without the chloride attack of HCl, making it safer for mixed-metal parts
