01 Decoding GLDA: A Green Chemistry Powerhouse

Tetrasodium Glutamate Diacetate (CAS 51981-21-6) is not just another chemical additive. Its foundational structure is derived from glutamic acid, a naturally occurring amino acid, marking its origin in renewable resources. This intrinsic design translates into a readily biodegradable and non-phosphorous profile, addressing one of the core environmental concerns associated with traditional, persistent chemicals.

The defining property of GLDA is its powerful ability to chelate, or bind, metal ions such as calcium, magnesium, and iron. This action is crucial in oilfield chemistry to prevent scaling, stabilize fluids, and enhance other processes. With a molecular formula of C₉H₉NNa₄O₈ and high solubility across a wide pH range, it is exceptionally stable and effective under the harsh, high-temperature conditions typical of downhole environments.

02 Key Chemical Identifier: CAS 51981-21-6

For procurement specialists, engineers, and compliance officers, accurate identification is critical. The CAS Registry Number 51981-21-6 is the unique, universal identifier for Tetrasodium Glutamate Diacetate (GLDA). This number ensures precision in sourcing, safety documentation, and regulatory submissions, guaranteeing that you receive the consistent, high-performance product your operations depend on.

03 Core Applications in Petroleum Operations

The application of GLDA (CAS 51981-21-6) in oil and gas fields is multifaceted, directly addressing key operational challenges:

• Scale Inhibition in Fracturing: During hydraulic fracturing, the compatibility between injected fluids and formation water is vital. GLDA is engineered to prevent the formation of carbonate and sulfate scales, which can severely damage reservoir permeability and well productivity.

• High-Temperature Stabilization: Unlike many conventional chelators, GLDA maintains its structural integrity and functionality at elevated temperatures, making it a reliable choice for deep-well and high-temperature, high-pressure (HT/HP) applications.

• Enhanced Fluid Performance: Its excellent chelation power helps maintain the stability of drilling and fracturing fluids. Furthermore, it exhibits a synergistic effect with biocides, enhancing their efficacy in controlling sulfate-reducing bacteria (SRB) and mitigating microbial-induced corrosion.

04 Aligning with the European Standard: Beyond Compliance

The European market is governed by the world's most forward-thinking environmental and safety regulations, including REACH. Choosing GLDA (CAS 51981-21-6) is a strategic decision that goes beyond mere compliance.

• REACH & Environmental Compliance: Its ready biodegradability and favorable environmental toxicity profile simplify regulatory compliance and support corporate ESG (Environmental, Social, and Governance) reporting.

• A Safe Substitute: GLDA is widely recognized as a direct, sustainable replacement for legacy chelating agents like EDTA and NTA, which face increasing regulatory scrutiny due to environmental persistence.
