The notes below summarize the cited references. Obtain the current SDS for the actual supplier, grade and destination before planning handling or shipment.
以下内容汇总所引资料。安排操作或运输前，请取得实际供应商、等级及目的地适用的最新 SDS
TCI’s 2026 Japan SDS specifies a tightly closed container in a cool, shaded area. Its product page recommends below 15 °C. Confirm the supplied lot’s label and SDS.
TCI 2026 年日本 SDS 要求容器密闭并置于阴凉处；产品页建议低于 15 °C。实际供货按批次标签和 SDS 确认。
The Japan SDS calls for dust containment, local exhaust, gloves and eye/face protection. The EU SDS classifies skin and eye irritation (H315, H319; Warning).
日本 SDS 要求控制粉尘、采用局部排风并配备手套及眼面防护。欧盟 SDS 列为皮肤与眼刺激（H315、H319；警告）。
TCI’s November 2025 EU SDS lists F0710 as not regulated as dangerous goods under ADR, IMDG and IATA. Confirm classification for the actual shipment and supplied grade.
TCI 2025 年 11 月欧盟 SDS 列明 F0710 不按 ADR、IMDG、IATA 危险货物管理。实际出运仍需核对供货等级及运输分类。
Confirm these points before approving a sample or supply route.
样品或供货路线确认前，建议核对以下事项
Specify HPLC and titration requirements separately. Request the batch COA, methods and acceptance criteria before confirming the specification.
分别约定 HPLC 与滴定要求；确认规格前索取批次 COA、检测方法及验收标准。
Agree application-specific limits for moisture, colour, inorganic residue and trace metals. Request a representative sample for your qualification work.
结合应用约定水分、色度、无机残留与痕量金属限度，并索取代表性样品用于评估。
If renewable feedstock is required, specify the origin criteria and request traceability records for the proposed manufacturer and supply lot.
如需可再生原料，明确来源要求，并索取拟供应商及供货批次对应的追溯资料。
Align quantity, packaging, delivery terms, current SDS and batch identification with the quoted material.
将数量、包装、交付条款、现行 SDS 与批次标识对应至拟报价产品。
03 / Build your specification
These details help compare supply options on the same basis. Start with what you know; mark the remaining requirements for discussion.
Confirm CAS 3238-40-2, the required chemical form and any grade or stereochemical requirements. Attach your specification if you have one.
State the required assay, analytical method and relevant impurity limits. Identify any tests or documents needed before sample approval.
Provide the trial quantity, expected production demand and whether the request is for a sample, qualification project or repeat order.
Include the delivery country, preferred packaging, required date and delivery terms so freight and documentation can be reviewed together.
04 / Quality & delivery
Request a COA, current SDS and relevant technical data, specifying whether you need an example or documents for a proposed batch. Agree the manufacturer, grade and document scope during the sourcing review.
No document files are attached to this catalogue record. Availability requires confirmation.
Packaging format, net weight, container compatibility and labeling are confirmed for the selected grade and shipment.
Request storage and handling conditions from the applicable SDS. Transport classification and any temperature controls require confirmation for the proposed shipment.
Agree the specification version, test methods and acceptance criteria first. Ask how the sample relates to the proposed manufacturer, grade and production batch, and record which documents will accompany the shipment.
Submit the required grade, quantity and destination. Commercial terms, current availability and delivery timing are assessed for that inquiry and confirmed in the quotation; catalogue inclusion does not establish stock or a delivery commitment.
